Eugene, I've got a 60D an have been shooting 50k+ pictures over the last year, so here's my 2 cents:
* concerning "wait" see the eos body timeline at http://www.northlight-images.co.uk/rumours.html
... I think they will replace the 7D first and then let the features trickle down
* articulating screen: when I bought the body I thought that this would be really useless for photos since pro bodies don't have it. I have been wrong, it really is useful - while I'm not shy to lie flat in the mud to get a good picture, you can get good *overhead* shots w/ the screen tilted down. And it's a nice protection when the lcd is turned inwards.
* same goes for the "plastic" body - it's actually quite solid, I have been dropping more than one time from shoulder height. What is likely to break is your non-L lens, not the body.
* imho, the 60D has no af because it does not really auto focus. It is a focus helper if the object you want to shoot happens to be near one of the 9 sensor fields. The servo af is extremely outdated compared to 7D/1D.
* the advantage of the 60D is that it is using balanced/proven technologiy, has good ergonomics and "just works". ISO noise is non-existant up to 200/400htp, and ok up to 800. I am shooting raw, and I really don't think a faster DIGIC would change the noise level significantly, using Lightroom4 or another sensor does this.
* last not least: the very most important advantage is that magic lantern works on 60D, you won't get this for the 70D when it's released.
